I'm not surprised. A WHOLE GRAM of DNA?! That's a lot. DNA is so small that you can almost see the molecules that make it up so it's quite close to atomic scale. To put so much stuff at that scale that it actually manages to weigh a whole gram means there's quite a lot of DNA in there, waaaaaaaaaaay more than any living thing has. Consider that extremely few cells(DNA, nucleus, and everything in it) weigh as much as a gram in the first place. Stable huh? I wonder in what fluid, cause in the open DNA decays within days after the death of its cell.
